Site description The Chimán Wetlands include extensive mudflats (11,400 ha), up to three km wide, and coastal mangroves (18,300 ha) from the Ensenada de Corral at the mouth of the La Maestra River eastward to Punta Bruja, at the base of the Serranía de Majé). The site merges with the Upper Bay of Panama IBA to the west. Short rivers from the Serranía drain into the area, including the Platanares and Chimán. There are small villages at Chimán at the mouth of the Chimán River and at Punta Brujas, and a few other settlements inland.
